when igo to start up my car after a day or two of not starting it (sr20) the rpms jump to about 1200 or so then as they begin to come down to idle (700-900) it begins to stumble and die
drops down to about 300 rpms
this problem goes away if i give it gas.
could it not be getting enough fuel on startup?
i checked for vaccuum leaks but dont see anything. after i give it gas it holds fine for the rest of the day anyways.
my mafs has a small inlet on the top of it, looks like a breather or hose should be attached to it.
theres nothing there right now, this is how the car was when i got it.
if i didnt drive it for a couple days, and when it came to be started… the rpms jumped in the beginning and then it would drop in a matter of 3 sec to 700 or so… and then sputter down and die
this happened after i got custom intake work done and after i got rid of my EGR… im still thinking its prolly the MAF but couldnt figure it out
I had a very simmilar issue with my SR and it turned out to be the timing. It was only ever on startup for 45 seconds it would want to stall otherwise it ran like butter all day. I know the timing was advanced to solve it but i dont know what it was set to.
Is this on my old car Matt. If so It used to do this with the KA24. the fuel filter was a brand new 300zx TT one so im doubting its that. It used to do this the most when I’d fill the tank from almost empty.
